Abstract: According to the communication requirements of multi-vehicle cooperative system, a design method of transceiver-integrated RF device with high isolation, wide dynamic and fast response is provided. This paper discusses the architectural of the transceiver-integrated RF device, and the key indexes as AGC circuit, high isolation, and linearity are designed from the engineering application. A high isolation transceiver-integrated 4×2 RF switch matrix is designed. Through the field test of the system, the test results show that the transceiver isolation index is greater than 99 dB, and the receiving dynamic range is greater than 65 dB. The RF indexes are stable and reliable to meet the needs of multi-vehicle system requirements, which provides a reference method for the further study of the multi-vehicle system data exchange equipment.
Key words : high isolation;transceiver-integrated;wide dynamic;fast response

引言

隨著機(jī)載平臺(tái)的機(jī)動(dòng)性能快速提升,對(duì)設(shè)備的通信性能也提出了更高要求,其中多機(jī)協(xié)同通信系統(tǒng)正成為世界各國(guó)的研究熱點(diǎn)[1-2],如圖1所示。該系統(tǒng)以時(shí)分多址為基礎(chǔ),并結(jié)合頻分、空分多址復(fù)合機(jī)制,利用每個(gè)時(shí)隙控制波速指向通信對(duì)象,能夠?qū)⑵脚_(tái)能力有機(jī)整合,載荷功能融入互補(bǔ),對(duì)促進(jìn)多樣化任務(wù)執(zhí)行能力、高效信息共享和協(xié)同行動(dòng)具有重要作用[3-5]。接收和發(fā)射設(shè)備為該系統(tǒng)的建設(shè)提供了硬件基礎(chǔ),同時(shí)也對(duì)收發(fā)設(shè)備的性能也提出了更高的要求[6]。目前的收發(fā)一體設(shè)備為提高收發(fā)隔離度、接收系統(tǒng)響應(yīng)時(shí)間等指標(biāo)性能,采用收發(fā)系統(tǒng)獨(dú)立的方式,存在體積大的缺點(diǎn)[7-10]。
